ALUMINIUM LABEL PRINTING
[EIRI/EDPR/1093] J.C.: 9737
INTRODUCTION
Cracking of the gun-arabic film on varnish impregnated aluminium, e.g for transparencies. This fault is identical with the cracking of short oil varnish film on long oil under coatings. The gun layer really takes the place of a very short oil resin film.
Label varnishes dry quickly without penetrating into the aluminium and other metal etc. while on account of its oil content and also of two sided application, transparent varnish can penetrate completely.
Some pigments contained in printing inks retard the drying of e.g roller coated clear varnish procure more suitable inks. Drying can be accelerated by one of the safe heating processes. If the varnish printed surface shows numerous amtt patches, the printing inks used may be unsuitable and too absorptive. Sometimes they do not accept super imposition of a lacquer at all (crystallation).
If the lacquering is streaky or cloudy, cold or draugghty working rooms are indicated, affecting flow. Alternatively, if application is by roller coating the rollers may need attention.
Spirit and cellulose lacquer film may also show cloudiness if susceptible to thigh moisture content of the atmosphere. The temperature for lacquering or varnishing should be 75o to 85oF (approx. 25o to 30oC). Good result has also been obtained by slight warming of the coating on the machine. Rollers should be even, clean and correctly set.
